Linking css and js doesn't work but an image does?


I just joined here. i had been using codepen which as we know takes care of linking css js to your index file. now im stumped as to why my preview isnt recognizing my links to css and js but is to my assets, since i have used the same type of relative path in both.

im going to try to share a link to my project which is an html 5 project.
EDIT: i figured out css. now i cant get it to recognize cdn to jquery
